Due to their high retail value, some edible oils are often blended wilfully with other more inexpensive vegetable oils. Two recent publications by Kim et al. and Krause et al. in international journals were able to demonstrate that Spinsolve 1H benchtop NMR spectroscopy is a possible cost-effective method for discriminating the authenticity of some vegetable oils.
Overlaid 60 MHz 1H‑NMR spectra of genuine patchouli oils spiked with 9 different adulterants at 20%.
Two recent publications (link here and here) in international journals highlight the potential of using the Spinsolve benchtop NMR for real time chemical reaction monitoring. Interest in using NMR spectroscopy to monitor chemical reactions has been increasing as the information can be used to optimise yield and minimise waste in order to enhance sustainability of the production process.
One of papers from the Ley group at Cambridge University (Musio et al., ACS Sustainable Chem. Eng, 2017) describes how real-time reaction monitoring on Fluorine can be used to optimise the reaction and reduce the environmental impact in the synthesis of functional fluorinated products. The other paper from the Blümich group at RWTH Aachen (Singh et al., Anal. Bioanal. Chem., 409, pp 7223–7234, 2017) evaluates the on-line benchtop NMR reaction monitoring method against off-line GC and high-field NMR methods and finds excellent agreement between them.
The Spinsolve is not only a perfect tool to teach NMR to Chemistry students, but its performance enables it to be used for serious research. This is evidenced in the published papers from our users. Over the last few months there has been a number of new publications featuring Spinsolve. In this post we will highlight a few of them. Click here for a full comprehensive list of publications.
